Reaction of Boundaries of Moistening Zones of the Russian Plains to the Climate Changes

E. A. Cherenkova and A. N. Zolotokrylin

Spatio-temporal moistening variations of subboreal plain landscapes of Russia and the reaction of boundaries of moistening zones to the climate changes as a whole are investigated for the period of 1936–2006 and for its certain intervals. The areas with homogeneous moistening variations and nonlinear moistening trends in every area are determined, coefficients are computed of linear trend of annual precipitation and evaporativity, of annual moistening, and of moistening for vegetation season on the whole territory. It is demonstrated that the boundaries of moistening zones of the territory for the period under consideration remained within the limits of interannual sample variability.
